A fluidized bed combustion system and method in which a recycle heat exchange section is located within an enclosure housing the furnace section of the combustion system. The flue gases and entrained solids from a fluidized bed in the furnace section are separated and the flue gases are passed to a heat recovery section and the separated particulate material to the heat exchange section. The heat exchange section includes a bypass chamber for permitting the separated solids to pass directly from the separator, via an outlet chamber, to the furnace section. A heat exchange chamber is provided in the recycle heat exchange section which receives the separated materials from the bypass chamber and transfers heat from the separated material to a fluid flow circuit for heating the fluid flow circuit and reducing the temperature of the separated material. The separated material in the heat exchange chamber is then passed back, via the outlet chamber, to the furnace section.

Fluidized bed combustion system and method having an integral recycle

A steam processing apparatus and method in which a plurality of separators are disposed along the length of a cylindrical drum having inlet means for receiving a mixture of liquid and vapor and outlet means for discharging the separated liquid and vapor. The mixture is discharged against a baffle after which the separated liquid is passed to the drum liquid outlet and the separated vapor is passed upwardly by natural buoyant forces to the drum vapor outlet. The separators are disposed in a plurality of rows--two to each side of the axis of the drum along the length thereof.

Steam processing apparatus and method

A fixed roller pulverizing mill wherein there is comparatively little wear, vibration or other adverse characteristics and wherein a uniform fineness of the ground material is maintained. The rollers, which do not move substantially in a horizontal direction, bear down on a rotating table, contacting the table at a circular trough therein and are individual spring biased to improve the performance of the mill.

A burner monitoring system in which an array of burners are viewed by a video camera adapted to produce a video signal representing the infrared image of the burner array. The video processing electronics processes the video signal to determine which of the burners is lit and which of the burners is unlit by the presence or absence of hot spots in the infrared image. The video processing electronics generates a video signal which is applied to a cathode ray tube device to generate a visual indication for each of the burners indicating the lit or unlit condition of each of the burners.

Burner monitoring system

A vapor generating system in which a vapor generating section and a superheating section are connected in a series flow relationship. The vapor generating section includes an upright furnace section formed by a plurality of tubes, a portion of which extend at an angle with respect to the horizontal plane for passing fluid through the length of the furnace section to convert a portion of the fluid to vapor or to heat the fluid. The angularly extending portion of each tube has a rifled bore.

A method of pulverizing is provided which allows for blending different pulverized solids before passing the pulverized solids to points of use. The method steps of pulverizing a plurality of solids feedstocks in a plurality of pulverizing sections, mixing the pulverized solids, and regulating the rates at which the solids feedstocks are fed to respective pulverizing sections.

Method of pulverizing

A furnace enclosure is provided in which one wall includes tubes of different passes which are free to move longitudinally relative to each other. A seal plate and filler means are disposed outside of the enclosure to provide for gas-tightness.

Furnace enclosure for vapor generator

A vapor generating system for use in a power plant having a steam turbine and a condenser connected in a series flow relationship, in which a vapor generating section receives a heat exchange fluid and passes the fluid in a heat exchange relation to a source of heat to raise the temperature and pressure of the fluid to predetermined values. The vapor generating section operates at substantially constant pressure during start-up and a pressure control station is provided which includes one or more relatively small bore tubes, a first conduit having control means disposed therein, and a second conduit, through which fluid passes before it is passed to a plurality of separators in the main flow path which receives the fluid and separates same into a liquid and a vapor. The separators are connected to a vapor circuit and to a liquid circuit for passing the vapor and liquid to the turbine and heat recovery or condenser, respectively. A method of starting up a vapor generating system in a power plant.
